DISCHARGING SKIP.

Application filed June 20, 1923, Serial No. 646,595. Renewed June 30, 1925.

To all whom it may 000721387 71."

Be it known that we, SAMUEL THOMAS FARNswoRTH, residing at Denby, Lancaster Road, Rose Bay, near Sydney, in the State of New South Wales and Commonwealth of Australia, and GERALD HAS- KINS, residing at Avon Dam, Via Bargo, in the said State, both subjects of the King of Great Britain, have invented a new and useful Improved Discharging Skip, of which the following is a specification.

This invention has been specially devised in order to provide an improved discharging skip specially useful in the construction of dam and like works and large concrete structures and whereby the contents or part thereof of the skip may be expeditiously discharged without tilting or overturning same and the discharge may be regulated as desired.

The improved discharging skip according to this invention comprises a receptacle or body with a contracted open bottom, a cone shaped closure for said open bottom, means for raising and lowering said closure to respectively close and open said bottom, means for protecting said bottom and the closure while providing for ready and convenient inspection thereof, and means for connecting said skip to and suspending it from a hoisting cable.

And in order that the invention will be readily understood a convenient and practical application of the same will now be described with reference to the accompanying drawings in which 2- Figure l is an elevation,

Figure 2 is a vertical sectional elevation,

Figure 3 is a plan, and

Figure 4 is a plan on the plane H in Figure 1.

The skip body or bucket 5 conveniently cylindrical and suitably constructed has a contracted bottom 6 with opening 7 therein and a protecting wall 8 around said bottom 6 and having observation or inspection orifices 9 therein. A vertically movable cone like closure 10 for the opening 7 is carried upon the lower end of a rod 11 vertically movable within a lower guide 12 upon radial arms or supports 13 from the bucket wall and in upper guide 14 of suitable formation between transverse bearers 15 at the mouth of the bucket and the upper end 16 of said rod 11 is hingedly connected by rod 17 hingedly connected to a crank 18 which is preferably adjustably affixed to a gear wheel 19 mounted upon an axle 20 in bearing 21 upon said bearers 15. Said wheel 19 is in mesh with an endless worm 22 upon a shaft 23 in bearings 24: affixed to the bearers 15 and bearing 25 upon the bucket wall and having upon its outer end a chain wheel 26. Afiixed to the top of thevbucket wall are lugs 27 to each of which is connected one end of link bars 28 to whose other ends is connected a shackle 29.

It is to be understood that the means described of raising and lowering the closure though suitable and eflicient may be varied as required or desired.

In use the closure 10 having been raised to close the opening 7 in the bottom 6 the skip is loaded and transported in any convenient manner such as by a crane, aerial rope way, or the like, to the desired point when the closure is lowered the requisite distance, according to the rate or quantity of discharge desired and the nature of the load, thus freeing the opening in the bot tom and allowing the contents of the skip to freely discharge without the necessity of canting or overturning the skip thus saving considerable time. When the load or desired portion of same has discharged the closure is raised to close the opening in the bottom.

We claim 1. A discharging skip, comprising an open topped bucket having a contracted bottom provided with a discharge opening therein, a vertically movable conical closure for said opening, means for raising and lowering said closure in relation to'said opening thereby to control the rate of discharge from said bucket, and a protecting wall enclosing said bottom.,

2. Improved discharging skip comprising an open topped body or bucket having a contracted bottom provided With a discharge Opening therein a protecting Wall around said bottom, a vertically movable rod carried by said bucket means for vertically reciprocating said rod, and a conical closure carried by said rod andadapted to open and close said opening in response to the reciprocations of the rod.
